【Abstract】 Nutrient condition in the soil planting carrot in Jinjiang was detected and analyzed in this paper. The results showed that the organic matter,alkali-hydrolysable nitrogen and phosphorus of soil are relatively lack,and the average content of organic matter was 8. 3 g / kg,among which,the soil samples in the middle and lower level account for 99. 6%. The average contents of alkali-hydrolysable N is 47. 0 mg / kg and the soil samples in the lack level account for 94. 8%. The average contents of available K is 71. 0 mg / kg and the soil samples in the lack level account for 73. 0%. The content of available phosphorus is rich with an average of 36. 6 mg / kg and the soil samples in the rich level account for 66. 8%. And the soil p H value is alkaline and 71. 1% of the soil samples are in a slightly alkaline and alkaline level.更多还原
